Title: Magnetic recording and reproducing device
Inventor: MURAOKA HIROAKI
IPC: G11B17/32
Filed: 1983-12-24
Abstract: PURPOSE:To maintain a stable position of a magnetic head to a recording medium having a large coefficient of friction by using a flexible metallic plate to support the head and giving a single mechanical freedom degree to the head in the direction approximately vertical to the surface of the recording medium. CONSTITUTION:A flexible metallic plate which fixes a magnetic head 10, i.e., a flexture 11 has V-shaped flexed parts 12 at four areas of the circumferential part and is fixed to a head support stage by attachment holes 13 at the outer circumference. Therefore, the mechanical freedom degree of the head 10 is limited only in the direction rectangular to the surface of a recording medium. Thus rotary motions of the head 10 are suppressed and the rubbing surface of the head 10 to the recording medium is always maintained in parallel to the surface of the recording medium.

IPC: G06F12/00
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a resource change notification method which effectively and asynchronously notifies other devices of the resource change of a computer. SOLUTION: A resource change notification client 200 sends the resource name, the change type, the check timing and the request message including a notification means to a resource change notification server 100. The server 100 receives the request message and checks via a check part 140 whether the resource name described in the request message is changed in the method that is pointed by the change type or not based on the check timing. If the resource name is changed in the corresponding method, a notification part 150 notifies the client 200 of the resource change.

Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To improve operability by selecting either of a file for protection of a copyright and a file for non-protection of a copyright as a reproducing file from a recording medium and executing changeover control of demodulation processing. SOLUTION: The music data recorded in a sheet memory 1 is encrypted for the purpose of copyright protection and voice data does not require copyright protection and is not encrypted. Corresponding to this, an encryption/ development processing section (SAM) 50 encrypts/decodes only the music data. When starting reproduction, a user selects the music data or voice data and carries out reproduction operation by operating an operation section 30. A CPU 41 makes the SAM 50 effective if the object for reproduction is the music data. Namely, a signal processing route is so constituted that the decryption processing of the cipher is executed relating to the music data read out of the sheet memory 1. The encryption/decoding by the SAM 50 may also be applied to the data of the information file added with a track management information file.

After moving the substrates 1 to a preparatory chamber 4, the holder is returned to the reaction chamber 2. NF3 26 is supplied and a high-frequency power 15 is applied under 0.3Torr to etch the Si3N4 on a window 10 by plasma etching. H2 27 is added to remove residual F. By this method, thin films can be formed with a good reproducibility.

IPC: F25C1/00
Filed: 1989-09-28
Abstract: PURPOSE:To obtain an ice heat storage device which solves a reduced performance coefficient and a reduced ice filling rate of a freezer by providing a nozzle for blowing air into a water tank bottom, an blowing air lower than 0 deg.C into the water tank by a blower to make ice and store heat. CONSTITUTION:A title device is adapted such that air existent at the upper part of an ice water tank 1 is circulated by a cold air blower 3 to jet the air from the bottom of the ice water tank 1. The circulated air is cooled to air lower than 0 deg.C by low temperature refrigerant in a cold air cooler 4 and fed into the ice water tank 1 in a bubbled state to separate ice. Thereupon, water in the ice water tank 1 is satisfactorily stirred by a rising flow of bubbles produced from a nozzle 2 located at the bottom and has wholly its uniform temperature state. Further, ice 11 separated by heat exchange with the bubbles 10 of temperature of 0 deg.C or lower is deposited on the surface of a water tank fluid as it is for heat storage. Moreover, cold air emanating from the fluid surface of the ice water tank 1 involves little water and is further cooled to predetermined temperature by the cold air cooler 4 and is blown into the ice water tank 1 by the cold air blower 3. Thus, the filling rate of ice can be increased, and any frost is not deposited on the device to prevent the performance coefficient of the freezer from being lowered.

Henceforward, the correction value of the memory circuit 9 is read out, and is calculated by a multiplier 3 through an LPF 2, and gain adjusted output is obtained. Besides, the selection circuit 1, the level detection and holding circuits 4, 5 and the memory circuit 9 are controlled by a control circuit 8.
